ADUM3150BRSZ-RL7

Overview

The ADUM3150BRSZ-RL7 is a six-channel SPI digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It supports up to 40 MHz SPI clock rates with a data rate of 250 kb/s per channel. The device features a 3750 Vrms isolation rating and operates on a single power supply ranging from 3 V to 5.5 V. It provides a common-mode transient immunity of 25 kV/µs and is housed in a 20-SSOP package.

Feature Summary

• Optimized for isolated serial peripheral interface (SPI) communication systems
• Integrates high-speed signal isolation with low propagation delay and jitter
• Provides galvanic isolation via proprietary magnetic coupling technology
• Supports simultaneous transmission of control signals and high-speed data

Applications

• Distributed control systems in industrial automation
• Programmable logic controllers (PLCs)
• Sensor monitoring applications
• Motor control systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required reel quantity and tape specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to surface mount assembly processes.

Selection Notes

Select this component when designing isolated SPI interfaces requiring high throughput and compact form factors. It serves as an alternative to discrete optocoupler solutions by reducing component count significantly. Consider the 3750 Vrms isolation barrier and 25 kV/µs CMTI for robust noise immunity in electrically noisy environments.

Part Context

This part belongs to the ADuM315x SPIsolator series, designed specifically for high-speed serial communications. The series leverages iCoupler technology to offer superior performance compared to traditional optocouplers. It addresses the need for faster system response times and higher data throughput in modern embedded architectures.
